Depth resolving power in near zone: Numerical results for a strip source

The problem of determining an unknown rectilinear source from the knowledge of its radiated field over a rectilinear bounded observation domain locate d in the near zone, orthogonal and centered with respect to the source is d ealt with. In particular, we firstly analyze the information content of dat a by means of the Singular Value Decomposition of the radiation operator. S econdly, the resolution limits achievable in the reconstruction are discuss ed by examining the effect of the key geometrical parameters of the measure ment configuration.
